The mysterious door next door certainly represents the end of one’s own world and the beginning of a mysterious, perhaps even a frightening one.
In this sense, the door next door is a symbol for the foreign and alien and all the feelings and impressions aroused by it.
However, next door also stands for the charming neighbour that you always see taking his dog for a walk and who one day reveals himself to be a talented harmonica player; or for the friendly girl from upstairs that you hear studiously practicing the violin every day; or for an old schoolmate that you run-in to by coincidence at the railway station with an accordion in tow.
Next door thus stands for ‘every man’ and is thereby the ultimate proof of the fact that music connects.
‘’Song From Next Door’’ also means that things just might not be so far away and detached as they seem, that if one really wants, everything can be within reach, perhaps even somewhere behind the door next door.
